POLYCHAETA was born from a passion for recreational fishing and a desire to provide a sustainable alternative to wild-caught bait. Over the years, our research revealed that polychaetes have far greater potential than bait alone, opening the door to new applications in aquaculture. Today, this journey continues through a technology platform dedicated to innovative marine solutions.


A Lovely Adventure

OUR STORY

2014

BEGINNING

The beginning

In 2014, Marwen Mokdad and Ahmed Malek, two biologist engineers, noticed a decline in natural marine worm populations through their marine worm export business serving the recreational fishing industry. They decided to develop a sustainable alternative and launched the first research on polychaete farming

2019

SUCCESS

The first success

In 2019, after five years of studying the life cycle of the Perinereis Cultrifera, we succeeded in controlling their reproduction using an in vitro fertilization technique. This breakthrough allowed us, for the first time, to complete their entire life cycle under farming conditions.

2020

TEST

Semi pilote

In 2020, we reached another milestone with the launch of a 50 m² semi-pilot production unit, where we successfully produced our first kilograms of polychaetes. During this phase, we developed a new stress-based reproduction method, more efficient than in vitro fertilization, which became the subject of our first patent.

2021

PILOTE

First Pilot Farm

In 2021, we established the first pilot marine worm farm in Tunisia, on the shores of the Bizerte Lagoon. Covering 350 m², the facility was designed to produce around one tonne per year under conditions close to the species' natural habitat.

RESILIENCE

A Necessary Change

In 2024, rising Mediterranean temperatures gradually made the Bizerte Lagoon less suitable for farming our species. We therefore decided to completely rethink our production process

2025

CHANGE

A New Generation of Farming

In 2025, we developed a RAS (Recirculating Aquaculture System), a closed production system that provides full control over farming conditions. A new pilot unit was established in southern France, and POLYCHAETA expanded its activities into premium feed and bioremediation through collaborations with research institutions.

2026

VALIDATION

Validation and Future Outlook

In 2026, our RAS production process was successfully validated, paving the way for a 5,000 m² industrial project on the French Atlantic coast. At the same time, our first results confirmed the potential of marine worms for premium feed and bioremediation applications.
